SPECIFICATION forming part of Letters Patent No. 289,338, dated Ncvenzber 27, 1883.

Application filed Octoherll, 1583.

To a whom it nmy concern:

Be it known that I, J ARvIs B. EDSON, a citizen of the United States, residing 'at Adams. Berkshire county, ll'lassachusetts, have in vented new and useful Improvements in Treat ing Material with Zylonite to Resemble Peb ble, Goat, French Calf, and Alligator Leather, of which the following is a specification.

This invention has for its object the production of an article which resembles leather having the finish of pebblegoat, French calf,

ing sheets of leather such as are technically process, and applying upon the surface of the same thin sheets of zylonite or a similar p yroxyline substance of a prop er color, and whichis applied by partially dislent by any of t-hewell'known solvents of such substances, and then subjecting the same to a pair of rolls or any gradually progressing compressing-surface-so that a split or side of leather, say, three feet wide i and six in length, will be under pressure for or thereabout, period of, say,

calf, or a period of, say, ten or fifteen minutes to produce an alligator-surface, by which pressure the leather and the zylonite will be united, and then partially dissolving or applying asolvent-such as collodionupon the exterior surface of the sheet of zylonite, and pro gressively passing it between a pair of rolls two hundred pounds, moreor less, and moved at aspeed of about ten feet per minute (more render a satisfactory gloss.

other similar surface, by which the exterior surface of the zylonite will be as finely polished pressed. A convert surface, beginning at the center of the split and gradually extending out to each end in the ease of such articles as are formed from sides of leather, willbe found to be the preferable method of applying (No spccimer s l may be effected simultaneously with the com bining operation, or before or after the same,

depending upon the nature of the surface to be operated upon and the degree of polish or gloss requirec. In some cases a simple treat ment with a fluid solvent, removing quickly the surplus, will, with a warm temperature, Whatever the result desired, it will be necessary in all cases to so operate as to prevent the solvent used for combining from being in excess or too long in contact with the thin sheet before placing in contact with the leather or base. I

The

therefore prefer applying the solvent gradually or progressively, and then in same manner almost immediatelyperform the pressing and combining operation, and thereby sin1ultaneously expelling the surplus solvent.

Having thnsdescribcd my invention, What I claim is 1. The method of making a substitute for leather resembling goat pebble, French calf, or alligator, consisting in partially dissolving the surface of a sheet of zylonite or similar pyroxyline substance by a suitable solvent; secondly, applying thesaid sheet to the material forming the base withthe partially-dissolved side of the sheet next thereto; and, thirdly, applying pressure for a period of time sufficient to imitate the kind of leather to be produced, and to expel the surplus solvent and air and cause an intimate union of the base and sheet of zylonite, substantially as described.

2. The method of making a substitute for leather resembling goat pebble, French calf, or alligator, consisting in partially dissolving the surface of a sheet of zylonite or similar pyroxyline substance; secondly, uniting said surfaces a thin sheet of zylonite or similar py= roxyline material having a polished surface in imitation of the leather mentioned, substanr5 tially as described.

In testimony whereof I. have hereunto set my hand in the presence of two subscribing witnesses.
